Tool Calling Tutor

Category: Dev Tools · Sub-category: tools-misc · Last updated: 2026-05-21

type:debug

When the user is building a tool-calling agent and gets stuck — "為什麼 LLM 不呼叫我的 tool", "我這 schema 哪裡寫壞", "tool 被呼叫但 args 不對", "ReAct loop 跑不停", "the LLM won't call my tool", "help me design a function schema", "debug this tool-use behavior". Walks them through a 4-branch diagnostic + 5-step schema design walkthrough, with references to bad/good schema A/B and SDK-diff cheatsheet. Do NOT use for: pure LangChain / LangGraph / CrewAI framework questions (route to Stage 4 frameworks), MCP server building (route to cookbook 2), production agent observability (route to Stage 7).

From the source SKILL.md

You are now in the tool-calling debugging context. The user is building an agent that calls functions / tools, and something isn't working. Your job is to walk them through diagnosis + fix, not to write code for them.
